My concern would be metal particles from the tapping operation getting into the cat. Possibly could take the exhaust pipe off and vacuum out the manifold. If the exhaust manifold is cast iron it is not easy to weld.
@@johncooper4637 Just use ample amounts of grease on the drill bit and tap, as well as use a shop vac with a crevice tool near the working area. I would also use a steel plug. Biggest risk is breaking off the drill or tap, since the cast iron is severely work hardened. Time and patience. o7
There's been a couple vids like a Ram 1500 fuel tank where he talks about going back to the video to see like a plug he forgot to connect when putting up the tank
I'm thinking this is a most excellent idea to document the existing conditions, do a preliminary diagnostic that is now public record, will aid the operator, stakeholders, taxpayers and perhaps, private owners to help them explain/justify the work. May also be useful for return work that was declined for various reasons. Do you or, can you tag a vehicle to a video so, you may search/find video for that vehicle or similar that pass thru your shop? Local, State, Federal government would love to have this level of accountability for their acquisitions dept. to maintain their motor pools.
I wish you would do more of these. It's like when you first sstarted and diagnosing was step one and seeeing whether the customer approved for repair. It's honest. I miss videos like this Ray.
On a high mileage work vehicle like this, I wouldn't recommend risking braking the exhaust bolts and opening that can of worms. Not worth it to you or the owner, to replace the exhaust manifold. That hole looks symmetrical and an easy fix just capping it with a short bolt or plug. Welding it closed wouldn't be my first choice. More value for the owner addressing the steering box leak, damaged steering linkage and coolant leak..
With 380K miles on it, I'd say they are getting their money's worth out of that truck and it makes sense to spend some money on most of the fixes you mentioned. With a few repairs now, maybe they can hit the million mile mark!
Truck needs some love that's for sure. Seems to be a lot of controversy regarding threading and plugging the exhaust manifold. Aside from that I'm wondering if losing exhaust gas and pressure on that side is having any effect on the O2 sensors for that bank. Hopefully we'll see this over on the main channel soon.
Your diagnostic and recommendation procedure seems solid to me. Addresses their concerns, recommend solutions, and build a relationship. That's what it's all about.
great way to give an accurate estimate for repairs on a vehicle. plus giving an over all review of the condition of the auto to see if it would be a good investment or not.
Having the diagnostic chain to follow helps me to understand what is going on, even though I won't be fixing much anymore. There is still value in having knowledge of why it is the way it is. Thanks Ray
One thing watching Ray has helped me with, as a non-mechanic, is to better understand WHY the shop takes three days and charges the hours they do for what used to be a simple job on 1980's vehicles. If I owned a vehicle that required something insane, like say, taking the valve covers off the change the fuel injectors? I'd be VERY tempted to leave it unlocked in a parking lot with the keys "accidentally" left on the seat.
This is a great idea for customers. The short & dirty. I inspected your car and this is what I found. This is a nice service to offer stand alone. Even if you never work on the vehicle.
We've come so far with components that no longer require regular maintenance, but squishy rubber bushings make me think fondly of the solid steel bushings on my '67 C20. Leaking petroleum products make them work better...so long as said LPP don't wash the grease out.
Love this type of video! Would love to hear the customer come back and say - Get 'r done! Fix the A/C properly, I'm keeping this truck for the long haul.
I like this type of video, too, Ray. I don't need to see you spending 5-10 minutes to screw in an actuator, for example, or watch you remove a wheel. I usually fast forward through those parts, which works for me and those who like to see every one of a dozen bolts removed from a part. Watching you diagnose a problem is interesting. Oh, and my initial thoughts on that hole was to tap and plug. That's why the hole was drilled, to tap it and install a sensor. Simply tap it and install a plug.
The steering work is going to cost a small fortune by itself, so If it's me I would choose the butcher method of welding or plugging the exhaust manifold. The radiator, if it proves to be broken, will also be pricey. I can only imagine GM will want an arm and a leg, and then how will you film videos? Maybe we check whether Dorman sells an aftermarket radiator... The Sierra appears to be in remarkable condition for a truck that has driven the distance to the Moon. In space there is no corrosion.
If someone send me a vid of what they diagnose, I would be ecstatic, they would have my business for as long as I live, and I would recommend them to everyone! Love that you started including the metric system as well, it's easier to relate to.
If this was the truck with a hole in the manifold, could a stubby carriage bolt have been put in the hole and welded over? Then there would be minimal chance of welding debris getting inside the manifold.
Stress the fact that the control arms and steering gear are most pressing issues and then coolant leak is second. AC is way at the bottom. The arms and steering components pose a public safety hazard.
I like the diagnostic video's the best and I like the shortness of them as I don't always have time in the morning for an hour long video. Either way, keep doing what you're doing.
If the customer decides to replace the manifold, best option is to soak the bolts with penetrating oil several times the day before. That way it will be easier to do the job.
I hate to break it to you, but you can not weld cast iron, you can braze it But weld won't stick. It might but its going to fall out. Drill and tap the hole and plug it. Has to be pipe threads because Cast iron expands and shrinks at different rates then steel. Best to use a cast iron plug.
12:45 ok, you can not wire weld cast iron and many welders can't do it, however you might be able to stick weld with the right rod and technics, in other words you cannot weld cast iron and some types can't be welded at all. This would require a highly skilled welder to plug that hole correctly. Your better off drilling and taping it for a cast iron plug.
Tap the hole in the manifold and install a plug.

Didn't see your comment until I posted mine. Knee jerk reaction.
@@johncooper4637 Greasing the flutes will capture the chips..
Tap and plug the hole or get a professional welder.
Man i wish i lived closer to florida.. o5 lly duramax head gaskets are needing changed. Amarillo tx is where i am.
I’d tap and plug the hole or install exhaust temp sensor
Diagnosis videos great way for a customer to see what you found wrong without them having to be there. Also helps you as documentation for yourself.
It is a good tool for communication to the customer. That way they can see it to.
There's been a couple vids like a Ram 1500 fuel tank where he talks about going back to the video to see like a plug he forgot to connect when putting up the tank
You already have the hole in the manifold just tap it and put a pipe plug in there.
Where am I wrong here?
For the high mileage, it seems that it was well cared for!
Why not just weld the manifold? or just tap and plug the hole?
he doesnt know how to weld. couldnt be sure it would hold
AC is important in the cold as it is used in the defrost setting to remove excess water from inside.

I love how you say 20°C is cold, that's literally a nice summer day here in Scotland lol
Same here in "sunny" Ireland.😂
I put something similar and got negative comments , it's a nice spring/summer day in UK lol
Same here in Finland ;) Summer start +15 C ;)
Yup, 20 C is a hot and balmy day in Eastern Ontario Canada😁 Shorts and T-shirt weather!
Farhenheit or Celcius, Ray speaks in deprecated measurements still.
I wish you would do more of these. It's like when you first sstarted and diagnosing was step one and seeeing whether the customer approved for repair. It's honest. I miss videos like this Ray.
This video reminded me I almost forgot about the doodly doo days
@@Onewheelordeal Yes, I miss that too. But I'm sure Ray will never miss that LOL He had to listen to it day after day for a long time.
Always liked the doodly doo.

Ray, as also said by others, Drill and Tap the hole and install a plug. It will last longer than trying to weld cast iron..
They sell o-ring kits for those lower hose connections too if that's just what it is vs replacing the whole hose.
I love the diags, keep them on the main channel!
With 380K miles on it, I'd say they are getting their money's worth out of that truck and it makes sense to spend some money on most of the fixes you mentioned. With a few repairs now, maybe they can hit the million mile mark!
I think you are giving the customer good options👍🏿😂
These diag videos are a great idea. Plus you can tell the customer to check them out and choose their route of repairs if they so choose.
For the miles that trucks looks to be in good condition.
You're a natural diagnostic connoisseur Ray. Enjoy your mechanical experiences passed on to all You Tubers audiences.
@taylor42779 yup short shorts weather in bonnie dundee...scottish summer 3 days ha ha ha ha

Great way for the customer to see what you see with the explanation, I would definitely be more inclined to follow suggestions of what has to be done
Your diagnostic and recommendation procedure seems solid to me. Addresses their concerns, recommend solutions, and build a relationship. That's what it's all about.
Short and sweet. Just as like them. Diagnosis and then repair later. Works for me thanks.
In Saskatchewan as well. 20* c, turn on air conditioner. Then go ice fishing 😅
Knowledge is power. Diagnose and follow where it leads. You are a master of your craft.
Disliked the video re-do the whole video without the loud nasty diesel running we cant hear you and its deafening us!
great way to give an accurate estimate for repairs on a vehicle. plus giving an over all
review of the condition of the auto to see if it would be a good investment or not.
I can't to see Ray welding bolts to the block again. Those were some of the best videos...😂😂😂
I admire the way you extracted broken bolts
They do that on Bus Grease Monkey too
Fantastic video Ray.... Lots of small-big Jobs on that truck

Braze the manifold, brass
Would love to see a lot more of your diagnostic videos.
Nothing quite like video evidence of the diagnosis.
This truck spent about a 3rd of its life hauling cattle and hay.
We've come so far with components that no longer require regular maintenance, but squishy rubber bushings make me think fondly of the solid steel bushings on my '67 C20. Leaking petroleum products make them work better...so long as said LPP don't wash the grease out.
Yes you can weld a cast iron manifold…..a welder can anyway. Hard to do if you are more of a mechanic/welder or hobbyist/welder…
Love this type of video! Would love to hear the customer come back and say - Get 'r done! Fix the A/C properly, I'm keeping this truck for the long haul.
My boss got payment once....instead of cash guy gave him a horse..no kidding...the horses name??
Boneus. Tru story.
Two videos in one day!?!? Killing it bro

You could also potentially tap and plug the manifold hole. If the hole is too big for a 1/8 NPT, see if the next size up would work.
My fave...everythings is to a give point...point given🤔
So how much is that? and when?
service truck... makes me think you should get buddybuddy with edison.
Ive got 422.486 on my 2011 shitvalanche!!!!

I just waited 8 weeks for a steering gear from GM for my ‘16 2500.
I like the diag videos the most, I think having them on the main channel would be good?
I would have just cut a 3/8 diameter bolt down to 1/4 long, and used it to fill the hole and then welded it in.
Less welding wire needed.
Drill and tap a NPT hole and use a NPT plug. It won't go anywhere.
You don’t get off that easy here. Dave sighting????
I agree with others, tap the hole and plug it! That is what I did on my 6.6 Duramax.
20 degs C , I’d be sweating me nuts off back here across the pond ! 😅
It would be cheaper to tap a thread into the manifold's hole and plug it. That way the owner can use it if they desire.
Instead of welding the hole, why not tap it and plug it?
(@3:32) No, this goes in the vault of viscosity, not all over the engine parts! So not cool. 😢
Nothing better than a DirtyMax video on hump day!!
Typical of high mileage vehicles. TSP sensor failure
It would have been a lot easier to use a short bolt in the manifold hole and weld it up. Less chance of failure. 😮😮😮
I like the diagnostic video's the best and I like the shortness of them as I don't always have time in the morning for an hour long video. Either way, keep doing what you're doing.
Why replace the exhaust manifold if you can tap it and plug it also to weld cast iron you need to preheat it and use a nickel rod
Saw the compressor clutch slipping when engaged!
Over a third of a million miles! Who says they don't make 'em like they used to.
And I know you probably did that cause this is an old video.
When its winter in florida its still summer temps for up north it seams likeand what are the day time temps for there in the winter months
Do not weld it with Mig!!!!! just tap it for NPT and put a plug in it
I'd like to see you buy an old car and restore it to safe operating condition for the road
Will fixing the hole eliminate the boost pressure issue?
run a tap in the manifold and put a plug in it,easier than welding cast iron!!
gday ray. 20 c is a hot day here at the bottom of newzealand. lol.
Just spot weld the hole. Give the customer the option.
Has anyone mentioned to tap the hole and.plug with a bolt yet?
Enjoyable feature - thanks..........
About the A/C - might be a leaky TXV..........
Good job, High milage trans service and rear diff?
why not just tap the hole in the manifold and install a plug in it.
Is that what they call a bonus hole these days ? 😆😆😆😆😆
Here is a comment, for the algorithm.
tap out the hole in the manifold and screw a bolt in?
quick and easy, drill, tap and plug the manifold
thats a lot of miles on a vehicle. Time for the parts cannon !
Drill and tap the hole and put a threaded plug in it
Why don't you drill and tap the hole for a pipe plug.
My 1999 Silverado has 361k
Well it helps to shorten the other channel some on video time 🤷
If the customer decides to replace the manifold, best option is to soak the bolts with penetrating oil several times the day before. That way it will be easier to do the job.
Otherwise hot wrench
Maybe also consider changing the screws to prevent breaking.
Keep up the diag videos.!✌️🇺🇸
Tap out the hole and screw a bolt in it...
Besides the spelling what is the difference between a GMC truck and a Chevy truck?
Trim packages and options
I hate to break it to you, but you can not weld cast iron, you can braze it
But weld won't stick. It might but its going to fall out.
Drill and tap the hole and plug it.
Has to be pipe threads because
Cast iron expands and shrinks at different rates then steel.

Could'nt you be able to tap the hole and add a plug?
The Towns People are 'all aware' we have a channel C.
Braze the hole in the manifold. Dont weld it.
Knew it was a GMC right from the beginning, paint jobs always peal off. 😂
Environmentally friendly water based pain
Drill and tap the hole for a plug or weld a short bolt in it.
great video... Skills
